To. ZZ whom it may concern:

Be it known that I, FERDNANDO'G. GRRI- son, a citizen ot' the United Statesyresidin at Fort lVorth, in the county of Tarrant an Late of Texas, have inventedV certain new and useful Improvements in Automobile- Radiators,.of which the following is a specitcation.

My invention relates to surface condensers of that type knownas automobileA radiator which so frequently leak owing to the l jarring and jolting of the vehicle.

The object of my invention is, therefore, to provide a novel construction of radiator whereby to do away with Aall soldered joints and otherwise prevent any leakage.-

In the accompanying drawings, in which' the jacket partly broken away. F ig. 4 is a' central vertical sectional view through the radiator complete, and, F ig. 5 is a pers ective view of one of the body plates detac ed.

In the practical embodiment of my idea, I construct the radiator body 410, through which extend the air Hues 11, of a pair of body plates 12, one of which is shown in Fig. 5.- As shown, and in' the conventional shape of radiator, the body l() is rectangular' and receives water to circulate therethrough to and trom the water-jacket of'tlie engine. The body plates 12 are st uuped or otherwise fashioned from suitable material such as iron, steel or aluminum, Wit-h integral i'langes 1? extending at right-angles from all sides, and are so formed that the flanges of one thereof, overlap the flanges of the other. The plates 12 are, of course, perforated to provide flue openings 14:, before being assembled, and, when assembled, are rigidly and permanently fastened by a seriesof countersunk rivets 15, so as to be flush With the outer surfaces of said plates, said rivets extending parallel with the edges of the :body entirely therearound. The outer overlapping tiange 134 is then thoroughly calked as indicated at 16 in Figs. 3 and 4, and after the tlues 11 have been secured in position through the openings- 14, the inlet pipe 17 secured, and the circulating pipe openings 18 in the inner plate 12 temporarily closed, the body may be thoroughly tested and if found to be without a leak, is ready for its jacket 19. Ordinarily this jacket 19 is of brass, and in severalparts which are sli )pcd over the edge of the body and soldered 1n place. In accordance with my present idea, however, I cast the brass jacket directly over the edgesof the body l0 and around inlet pipe 17, and thus not only do away with'all soldered joints but effectively prevent displacement of the calking 16.

It will, of course, be understood that the size and number of the air flues 11, form no part of this'invention.

1. In an automobile radiator, the combination of a body comprising a pair of plates ,riveted adjacent their edges and having integral flanges, the flanges of one plate overlapping those of 'the other,'calking disposed between said flanges, and a solid jacket cast directly about the edges.

2. In an automobileradiator, the combination of a pair of body plates having integral flanges, the flanges of one plate overlapping those of the other, rivets connecting the body portions of said plates and extending in a series adjacent, and parallel with, theinner longitudinal edges ot' said flanges whereby to provide the outer edges of the flanges free to receive ealkin", and a jacket 'cast directl about the flange( edges of .said plates, the lnner edges o f said jacket extendmg inwardly and covering the rivets.

In testimony whereof I aflixiny'signature in presence o two witnesses.
